Bethanyc Posted July 25, 2020 Report Share Posted July 25, 2020 Hi link team, is there anything special on the DI10 interface on the G4X Evo 4-8 PNP board (ECU plug pin #46) i cant seem to get a simple switch setup on this interface, it should be straight forward, i have grounded one side of switch, and confirmed it is working at the ECU plug. I know this DI was originally assigned clutch switch, which is disabled in the config. (which my Evo also does not have) i might try move the cable to DI 5, 6 ECU pin in the morning, as these are also not in use on my Evo.

Adamw Posted July 25, 2020 Report Share Posted July 25, 2020 As far as I can see DI10 should be fine for general use, there is nothing special connected to it internally. Do you have ~12V on that pin with the switch off? Quote Link to comment Share on other sites More sharing options...
Bethanyc Posted July 25, 2020 Author Report Share Posted July 25, 2020 Thanks Adam, must be a bad ECU plug pin wire not making connection, its not seeing any voltage with the switch off. Ill swap it out , else try one of the other spare DI inputs. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 25, 2020 Report Share Posted July 25, 2020 Have you got the right pin? Bottom right corner of the 16pin connector: Quote Link to comment Share on other sites More sharing options...
Bethanyc Posted July 25, 2020 Author Report Share Posted July 25, 2020 Yes its 100% the correct pin. The yellow/ red wire with connector on it. Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 26, 2020 Report Share Posted July 26, 2020 That crimp join looks pretty dodgy from what I can see of it. How about if you poke a paper clip down into the connector beside the wire to measure directly on the terminal? Quote Link to comment Share on other sites More sharing options...
Bethanyc Posted July 27, 2020 Author Report Share Posted July 27, 2020 ok a quick update after testing this morning i tried a brand new pin plug with bare wire nothing connected into connector 46 DI10 > no voltage I then moved the same new plug pin to spare connector number 44 DI5 > reading about 10.4v , my switch works perfectly. so there is an issue with DI10 on the ECU... i dont need any more inputs and i have DI6 i can use as well if i need another. Its just very strange. Thanks. Beth. Quote Link to comment Share on other sites More sharing options...
Mizan Posted March 28, 2021 Report Share Posted March 28, 2021 Hello guys, just manage to get my hands in the g4x for the evo pnp.. as for pin 46 issue.. i think that links my have a printed error.. for other evo that have a clutch switch it will be assigned to pin 43 not pin 46.. pin 46 will be for fuel level tank input.. iam having the same issue here to assign a clutch switch to make the DI10 to work.. but now reassign the clutch switch to DI3..

Adamw Posted March 28, 2021 Report Share Posted March 28, 2021 I have no good info about which pin the clutch switch is connected to in a factory car, but I can tell you 100% DI10 is pin 46 on our ecu. Quote Link to comment Share on other sites More sharing options...
Mizan Posted March 31, 2021 Report Share Posted March 31, 2021 Thanks for the reasponse adam, but it took me several attempts to see DI10 on pin46 but no luck.. recheck connection and all is good.. lastly just switch to DI3 and it works... But according to original clutch switch pinout ot evo ecu its on pin 43.. Quote Link to comment Share on other sites More sharing options...

Mizan Posted April 2, 2021 Report Share Posted April 2, 2021 Got it on the website.. https://www.roadraceengineering.com/evo/tech/EVO-ecuwiring.htm ive done several conversion for oem evo ecu in which some customers who wanted the flatshift to be activated and i usually do it on the pin 43. would be great that to update the manual to help others.. but this is based on our jdm/audm model in asia.. hope this helps..

Grant Baker Posted April 4, 2021 Report Share Posted April 4, 2021 From OEM Wiring diagrams... Clutch switch is on Pin 43 Fuel Level is on Pin 46 Clutch switch will need swapping to Pin 46 to make it work with Link. Quote Link to comment Share on other sites More sharing options...
